摘要
采用Haar小波分解构造误差驱动的曲线数据压缩算法。对求得的少量重要数据点,运用保型性好计算速度快的通用参数化曲线插值方法,最终求得满足要求的三次B样条曲线。本文算法适用于大量密集数据点的快速曲线重构。
In this article, a data compression algorithm driven by tolerance was constructed based on Haar wavelet decomposition.For the important data, a fast and shape-preserved interpolation method based on universal parameterization was used to construct 3 degree B-spline curve satisfied requirements. The method in this article is suit to fast curve construction of a mass of dense data.
